Do you find your machine getting hot all the time?
Do you find your machine shuts itself down after an hour or so?
Having problem seeing the screen clearly?
You might have an issue with the laptop overheating. Normally, a bit of heat doesn't affect the machine too much but if the heat increases it can start causing problems.
The main reason for a machine to overheat is due to the dust build up.
All machines will eventually get a dust build up, which is why we recommend to get the fan cleaned at least once a year (more often if you're in a dusty environment or you smoke).
Performing a fan cleaning could save you over £100 in repairs!
